HAT FELTING AND SIZING MACHINE.

Application filed December 6, 1883.

To all whom it may concern:

Be it known that I, THOMAS LONGSHAW, a citizen of the United States,a'nda resident of East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Hat Feltingand Sizing Machines, of which the following is a specification.

My invention relates to that class of machines which are used in theprocess of hatmaking known as felting or sizing. This part of the workis generally performed by hand-labor, which is slow and tedious, andwhere-machinery has been applied it has met with serious objections byspoiling the stock;

- and when performing the work satisfactorily by machines the product isso small in advance of hand-labor that it does not repay the expense ofconstructing the machines.

The object of my invention is to devise and construct a machine thatwill meet all the requirements of the process, and perform the work morerapidly and successfully than has been done heretofore. I attain this bypassing the roll of hats between a revolving drum and a series of smallrolls fixed to a suitable frame around the said drum,and said rolls Iprovide with a suitable adjusting device for increasing or decreasingthe space between the rolls and the drum uniformly throughout the wholeof the circle, which is an essential feature, as the roll of hatsrequire an even pressure throughout the process of sizing; and properprovision is also made for keeping roll of hats warm, which willhereinafter be more fully explained, reference being had to theaccompanying drawings, in which- Figure 1 represents side elevation offelting and sizing machine. Fig. 2 represents plan view of same. Figs.3, 4t, 5, 6, 7, 8, 9 show several different ways of constructing thedrum. Figs. 10, 11, 12 show different forms of small rolls.

Similar letters refer to similar parts throughout the several views.

A represents frame; B, drum; 0, watertank; D, pressure-rolls; E, rollsof hats.

The drum B is supported by suitable bearings, a, on the frame A, and isrevolved by the belt-pulley F in the direction of arrowpoint to theinner side of the frame A at b.

(N0 model.)

The levers G are pivoted, and to the other end of the said levers isattached the pressurerollers D D, moving to and from the drum B by thelevers G, swinging on the pivot 12, and said rollers are retained andadjusted to any desired distance from the drum B by the circular frameH, having therein slots f for the reception of the protruding pins d onthe levers G. The said frame H is supported and rotated on the axle ofthe drum B by suitable arms, H.

On the upper part of frame H is an arm, H extending above the frame A,to which the swivel-nut e of the adjusting-screws his attached. Byturning the adjusting-screws h in either direction the nut e will travelforward or backward,rotating the frame H around the drum B, and changingthe position of the rollers D uniformly throughout the whole circle orseries by the pins (1 on lever G, moving freely in the slots f of theframe H, and the distance between the drum B and the pressurerollers Dwill be equal in any position they may be placed.

The pressure-rolls D may have a slide attached at each end, instead ofthe lever-,whieh will move to and from the drum B in a radial line byproper guides on frame A, and operated uniformly by projecting pins onsaid slide engaging with oblique slots in frame H.

The machine is placed in a tank, 0, of water,

which immerses the lower part of same to the height of water-line, andis kept to any desired temperature by steam-pipes Z. steam is alsoadmitted into the drum D to warm it by the steam-pipe s, passing throughthe spindle of the drum B, heat being an important featureinmanipulating the goods. To operate the machine the drum B is revolved inthe direction of the arrow-point. The roll of hats E is fed in from thetable K, and is carried around the drum B, between the same and thepressure-rolls D, and is delivered into the slide or trough K, and socontinue until the batch has all passed through the machine, when theyare examined and again rolled up and passed through the machine in themanner described, the space having been properly adjusted between thedrum B and pressure'rolls D by the screws h, as heretofore described.

Ajet of In some some instances it may not be essential to revolve thedrum continuously in one direction, but to make part of arevolution, andto reverse and revolve it inthe opposite direction a part of thedistance traveled in the forward direction.

The face of the drum B may be constructed in various ways by grooves orprojections, as shown in Figs. 1, 3, 4, 5, 6,7, 8,9. In Figs. 1, 5, 6, 7the face of drum is grooved in different forms, and are parallel withthe axis. In Fig. 8 the grooves or projections are annular. In Fig. 9they are at an angle. In Fig. 3 theface of the drum consists of a seriesof small rolls rexwlving freely in the head or end of drum. In Fig. 4 aseries of rolls are placed in a suitable frame.

Around the drum and on the periphery of the drum a rubber tire, a, isfixed, which revolves the small rolls by frictional contact with same.

The face of the drum may be covered with smooth or serrated rubber, ifdesired.

Figs. 10, 11, 12 show different forms of small pressure-rollers D.

I am aware that hat-rolls have been sized by revolving them between aseries of pressurerollers placed around an oval shaped disk or drum; butI am not aware that hat-rolls have ever before been passed between acorrugated revolving drum and a series of pressure-rollers adjustablyfastened to the inner circumference of a circular rotating disk orframe, as shown, and heretofore described.

\Vhat I desire to secureby Letters Patent 1. In ahat felting and sizingmachine, with a revolving drum and a series of pressurerolls, the leversG, pivoted to the main frame A at a point, I), tangent With theperiphery of the drum and attached to the roller D,and connected byslots or pins to the moving frame II, for adjusting the rollers D to orfrom the drum 13, substantially as and for the purpose specified.

2. In a hat felting and sizing machine with a revolving drum, themovable frame or disk H, rotated on the axis of the drum, and providedwith slots or pins connecting with the levers G, and operated by thescrews h and swivel-nuts e, substantially as described.

3. In a hat felting or sizing machine with a revolving drum, the lever Gpivoted to the frame A at b, and attached to pressure-rolls D,

being connectedto the movable frame or disk H by slots and pins, thesaid frame H rotating on the axis ofthe drum B,and operated by screws hand swivel-nuts e, substantially as and for the purpose specified.

4. In a hat felting and sizing machine, the revolving drum B, withcorrugated or plain surfaceplaced inside of the series of adjnstablerolls DD, substantially as and for the purpose specified.

5. In a hat-felting and sizing machine, the rollers D D, placed alongthe inner circumference of the rotating frame H, in combination with thelevers G, frame A, and rotating frame H, substantially as and for thepurpose set forth.

Signed at Bloomfield, in the county of Essexand State of New Jersey,this 4th day of December, A. D. 1883.
